If I want to use my TV to play PCSX2 games with Direct3D11 Hardware (connected with a HDMI cable) I get a black screen in PCSX2 (even the full boot is a black screen).
If I remove the HDMI cable of my TV, I'm not getting a black screen.

With Direct3D9, this problem is existant. Two monitors are working fine with it.

Because Direct3D11 is much better and my GPU is supporting it, I'd prefer Direct3D11 and use it instead with my TV.

My hardware:
CPU: i7-2760QM with Intel HD3000
GPU: nvidia GT555M (this one is used in PCSX2).

no problems here and he has probably the same laptop/set-up as mine, if you are connected to the tv, rightclick on the desktop and select screen resolution, and select the tv as main monitor. the screen should be black now on the laptop and you should have the desktop on your screen now.

if you start pcsx2 and play a game dont go into fullscreen just yet, see if it plays accordingly, if it does, alt and enter to go fullscreen. (or double click if you have that in the settings enabled
